wi ling and setting mechanism particularly dc 118C to reduce the number of parts empl ed to the minimum, wh reby chcapness of construction is secured and liability to derangement avoided. In another view of my invention, is designed to dispense with the use of the wheel-carrying yokes hereto fore employed in kindred watch structures.

With these ends in view, my invention consists in ivotal shifting-lever adapted to be coupled with the winding-and-setting stem and to shift a winding'and-sctting wheel from the wii Iig train to the setting t on and vice versa and laterally movable for disengagement from and ret ngagement with the stem. My invention further consists in further details of construction as will hereinafter be described and pointed out in the claims.

In carrying out my invention as herein shown, I employ a depending shifting-lever 2, mounted at its upper end upon a shoulder 3 at the outer end of a spacinghub 4 on an arbor the rear end of which has rocking and sliding movement in the rear movementplate 6, the forward end of which has rocking and sliding movement in a spacingbushing 7 mounted in the front movementpiate 8 and extending rearward therefrom between the two movement-plates.

The sa shifting-lever 2 is formed with an upwardly extending coupling-arm 9 bent to form a three sided clearance space 10, and having its forwardly bent upper end formed with an open slot 11 for the reception of a coupling-terminal 12 at the lower end of the removable winding-and-setting stem 13, which is furnished with the usual crown 14. the said stem having a squared portion 15 located adjacent to its couplingterminal 32 and passing through a squared opening formed in a primary stem-winding and stem-setting wheel 16, arranged at a right angle to the stem and mounted upon a horizontal bridge 17 located between the upper edges of the plates 6 and 8 at the bot-- tom of notches 18 therein.

The lower end of the shifting-lever 2 is formed with an angular shifting-slot 19, having an upper arm 20 and a lower arm 21, the upper arm having an inclined operatingface 22, and the lower arm having a lock ingundeicut The said slot receives the rearwardly projecting end of the laterally movable pivot 21 of the secondary windingaud-setting wheel 25, which constantly intermeshes with an intermediate windingand-setting wheel 26, mounted upon the outer face of the front movement plate 8 and in turn constantly intermeshing with the primary stem-winding and stem-setting wheel 16.

The pivot 21 has lateral movement in a slot 27 formed in the front movement-plate 8, its forward end projecting through the said slot and carrying the wheel 25 aforesaid. A collar 28 integral with the pivot 21f. bears upon the inner face of the front movement-plate, and coacts with the wheel 25 in preventing the longitudinal movement of the pivot, while not interfering with the lateral movement of the pivotin the slot 27, which is made sufficiently long to provide for the lateral shifting of the wheel so as to intermesh it with the main winding-01 plate wheel 2-) or the plate setting-wheel 30. The periphery of the collar 28 is engaged by a spring 31 applied to the inner face of the front movement-plate and exerting a constant effort to maintain the pivot 21 in the left-hand end of the slot 2? (Fig. 1), and hence the 'wheel 25 normally in mesh with the main winr ingor plate wheel 29.

:Tormally,.thc shifting-lever 2 is maintained in its forward or operating position in whi h it is coupled with the couplingterminal 12 of the stem 13, by means of a shoulder stud 32 11), mounted in the upper edge of the rear movement-plate 6 and having a portion of its head cut away to clear the arbor when it is desired to shift the lever from front to rear, that is, from the position in which it is shown in Fig. 3, to the position in which it is she vn in Fig. whereby the slotted coupling-arm 9 of the lever is cleared from the coupling terminal 12 of the stem 1? to permit the same to be removed or replaced. (Then the lever 2 is moved from front to rear as d -ribed, the rear face of the spacing-hub -iengages with the inner face of the rear movement plate and so limits the rearward movement of the arbor on the other hand, the movement of-the arbor 5 from rear to front is limited by the engagementof the shoulder 3 of the hub 1 with the spacing-bushing '4' in the front movement-plate.

Normally, the watch is set for winding, at which time the spring 31 engaging with the collar 28, holds the laterally movable pivot 2-1- in the left-hand end of the slot 27. whereby the wheel is maintained in mesh with the main windingor plate wheel 29.

At this time, the rear end of the pivot 24; will be located in the upper arm 20 of the angular shifting-slot 19, as shown in Fig. 1. If ow if the stem 13 is pulled outwardly by crown H, the inclined operating-face 22 of the arm 20 of the slot 19 will act upon the lower face of the pivot 2-1 and cause the same to be shifted to the right-hand end of the slot 27 against the tension of the spring 31, when the secondary winding ant setting wheel 25 will be demeshed from the main wimling-wheel 29 and intermeshed with the plate setting-wheel 30, as shown in Fig. 2. The lifting of the lever 2, as described, causes the pivot 21 to enter the lower arm 21 of the shifting slot 19 and ride into the locking-undercut 23 thereof, whereby the lever 2 is locked in its lifted or setting position, in which it will be retained by the said undercut 23 during setting. When the watch has been set, the stem 13 is pushed inwardly with the effect of swinging the lever 2 from right to left, causing the pivot 21 to ride out of the undercut 23 and out of the arm 21 of the shifting-slot 19 and resume its normal position in the upper arm 20 of the said slot, in which it will be retained by the spring 31 until the stem is again pulled out for setting the watch. By my improvement I omit the use of a pivotal yoke or lever carrying one or more wheels of the winding and setting mechanism and reduce the number of parts as well as liability to derangement. In my improved mechanism, the secondary winding-andsetting wheel 25 is mounted independently of the part-the lever 2bv which it is shifted for changing from winding to setting and Viceversa.
